Title: Improvements in hydraulic radial piston pumps and motors
IPC: F01B1/06
Filed: 1966-04-25
Abstract: 1,104,604. Reciprocating pumps and motors. REDERI AB SOYA. April 25, 1966 [May 5, 1965], No. 18048/66. Heading F1A. In a pump or motor having a track ring 22 mounted in a casing 40 and a rotatable cylinder block 12 provided with radial pistons 18 mounted on a pintle valve 10, the cylinder block and pintle are displaceable relative to the track ring to vary the piston strokes and further displaceable relative to the track ring in response to the difference between the pressures in the pintle passages 28 and 30 such that the angle between the plane in which the cylinder ports open to the pintle passages and the plane in which the pistons reach their dead centres increases with decreasing piston strokes and vice versa. The holder 42 for the pintle 10 is movable by means of lever 46 to vary the piston strokes and pistons 54, 66 in the holder and subject to the pressure in pintle passages 30 and 28, respectively, cause the holder to be moved in a direction perpendicular to the movement caused by lever 46.

Title: Anti-filling cap for the closure of receptacles
IPC: B65D49/04
Filed: 1966-04-25
Abstract: 1,138,326. Non-refillable bottles &c. ALLUMINIO MAUCERI BORGHETTO S.p.A. 25 April, 1966 [30 April, 1965], No. 18049/66. Heading B8D. A valve member 8 of a stopper adapted to prevent re-filling of a bottle &c. is screwed on to a stud 10 on a cap 1, the threading being in the reverse sense to that by which the cap 1 is attached to a body 2 rigidly attached to the bottle &c. (not shown). Thus when the cap 1 is unscrewed from the body 2 the valve member 8 initially remains joined to the stud 10, and is lifted from an aperture in a gasket 3, overcoming any tendency for the valve to stick in the closed position. The threading between the stud 10 and valve member 8 is relatively steeply pitched, so that during further unscrewing of the cap from the body 2 the weight of the valve member 8 causes it to rotate faster than the cap 1 and unscrew from the stud 10. The cap 1 may thus be completely removed, permitting pouring of the container contents. A disc 5, attached to the body 2 by ribs 4, prevents the complete disengagement of the valve member 8 from the body 2, thereby preventing re-filling, the stud 10 passing through a hole in the centre of this disc, which also serves to catch drips. An internal skirt 6 depends from the disc 5. Strengthening ribs 7 are provided on the gasket 3. To facilitate initial insertion of the stud 10 into the threaded hole in the valve member 8, a multi-start thread may be provided thereon, the flanges of the threads being tapered. The threaded aperture in the valve member 8 may also be flared as shown.

Title: Improvements in ionisation counter tubes
IPC: H01J47/08
Filed: 1948-07-06
Abstract: 649,618. Discharge apparatus. SHELTON, E. E., and TOMES, G. A. R., (trading as 20th CENTURY ELECTRONICS). July 6, 1948, No. 18181. [Class 39 (i)] A process of producing ionization counter tubes having a filling of vapour at low pressure comprises the steps of first inserting at one station an excess of vapour derived from a liquid source and then subsequently at another station removing the excess to give the required final pressure. The apparatus comprises a plate moving in the direction indicated by the arrow A to carry the tubes through stations 1 to 16. At the early stations the processes of loading, leak detection and exhausting are carried out, an oven o being provided over positions 3 to 10. The tubes are cooled at station 11. A vessel a containing ethyl alcohol or any other liquid quenching agent is connected to station 12 and vapour is fed into the tube at a pressure in excess of that ultimately required, the circuit of an electrical heater c being closed by a mercury manometer b when the vapour pressure falls below the desired level. The excess vapour is removed by a vacuum pump e connected to station 13 through a manometer d, the final pressure, for example 1 cm. of mercury, being determined by the depth to which tube f dips into the low vapour pressure liquid in the manometer. The filling of argon, or other permanent gas, at a pressure of say 10 cm. of mercury, is introduced at station 14 by any known process. In the arrangement shown, a vessel p contains argon which passes through a reducing valve g and an absorber h containing P 2 O 5  or metallic evaporated barium to the station, the pressure being indicated by a manometer i. The tube is sealed off at station 15. Stations 12, 13, 14 and 15 may be connected as required to vacuum pump e by pipes k, l, m and n, controlled by suitable cocks or valves. This is necessary on first starting the machine, or if a leaky tube accidentally goes round the machine.

IPC: G11C19/04
Filed: 1956-06-14
Abstract: 869,069. Circuits of bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. June 7, 1957 [June 14, 1956], No. 18399/56. Class 40 (9). [Also in Group XIX] In an intelligence store having a group or groups of storage cells, the cells of each group are selected sequentially and cyclically, intelligence from a selected cell being transferred to a temporary store and replaced by intelligence from a previously selected cell. As described, the " cells " are formed by holes in blocks of ferrite with "row" " and "column" wires threaded through. A column of storage cells 1, 2 . . . n . . . x - 1 are selected in turn by an access selector (not shown), each cell having a waveform applied thereto comprising a " read " pulse followed by a " half-write " pulse. Data may be entered at G6 as a series-mode train of " half-write " pulses in synchronism with those from the access selector. During the following cycle of the access selector each cell storing a " 1 " will be reset by a " read " pulse, thus producing an output pulse in the common column wire connected to a time-delay amplifier TB1; this pulse is stored in a bi-stable device MS1. During the next " read " pulse, a synchronized pulse at input e clears the store MS 1 for possible reception of a signal read-out from the next row, and the resulting output signal from MS1, after passing a further time-delay amplifier TB2 and a gate G5 (fed also by a " half-write " pulse at b), appears on the column wire as a " halfwrite " pulse in synchronism with the next " half-write " pulse from the access selector, thus re-entering the information into the storage column with a shift of one row position. However this shift is nullified by a corresponding shift of one step in the " home " position of the access selector. To provide for relative " left " and " right " shifts, further paths are provided in the feed-back circuit; the information signals may be fed back immediately through a gate G3 without being held in a storage element, or after further delay in a second bi-stable store MS2 via a time-delay amplifier TB3.

Title: Improvements in and relating to oil-filled cables
IPC: H02G15/26
Filed: 1929-06-19
Abstract: 313,928. General Cable Corporation, (Assignees of Atkinson, R. W., and Simons, D. M.). June 19, 1928, [Convention date]. Cable joints. - Oil-filled cables are connected together while the lengths are maintained full of oil, and the oil in adjacent cable lengths is not in communication. The conductor 13, Fig. 1, having a central oil channel 14 and porous insulation 12 impregnated with oil and an internally fluted lead sheath 4, is capped before jointing to prevent escape of oil by means of a plug 22 and thimble 15 soldered or otherwise attached to close the channel 14, and an insulating tube 8 attached at one end by a bushing 6 to the sheathing 4, and at the other end making joint with the thimble 15 through a pair of abutting rings 17, 18 screwed respectively onto the thimble 15 and into the tube 8. These capping operations may be performed while the cable end is immersed in oil. The thimbles 15 of the adjacent cable ends are connected together by a sleeve 16 having right and left handed screw-threads. Between the tube 8 and the outer Insulating tube 11, which is of wrapped paper with or without a moulded portion 10 and is either slipped on or built up in situ, are arranged condensers 9 comprising plates 28, 29, Fig. 2, connected in series, the outer ring 24 on one being connected to the inner ring 23 of the next, and one end of the series being connected to the sheathing by means of the bushing 6, and the other end to the conductor 13 through contact pieces 20. The series of condensers may be built up as a unit ready for application to the joint. Orifices 37 temporarily closed by a ring 7 place the oil in one cable end in communication with that supplied to the joint casing 1 from reservoirs 40, Fig. 6, having compressible air chambers 41 to allow expansion of the oil without undue variation of pressure. Air under pressure may be supplied from a pipe 44 and oil under pressure from a pipe 42. Connection pipes having valves 43 are provided to enable the oil to be applied to the joint casing 1 either from the reservoirs 40 or direct from the pipe 42. Valve casings 45 situated between the pipe 42 and the joint casings prevent intercommunication of oil from one joint to another by the provision of a valve 46, Fig. 7, that is opened against a spring 48 only when the pressure of oil in the joint casing acting on a diaphragm 47 exceeds a predetermined amount. The valve 53 by which oil passes into the joint casing is restricted either in area or by means of packing 54 to limit the rate of flow of the oil. A terminal structure 30, Fig. 4, comprises an insulating tube surrounding the oil-impregnated insulation 12 and surrounded by a number of condensers 33 connected in series between the conductor 13 and the sheathing 14. An adaptation of the joint for a three-core cable is described. Specifications 7766/14 and 247,143 [both in Class 36, Electricity, Conducting. &c.], are referred to.

Title: An improved method of making a fibre fabric for filtering purposes
IPC: D04H3/14
Filed: 1957-06-14
Abstract: A fibre fabric for cigarette and other filters is made by orientating spun fibres substantially in a direction in which they leave the spinneret or spinnerets, crimping the fibres, arranging them in the form of a band, applying tension to the band to partially elongate the crimped fibres and applying a bonding agent to the tensioned band so as to form a band both longitudinally and laterally coherent and wherein the fibres are fixed in an elongated state.  Cellulose acetate fibres to 8 to 15 single denier and 80,000 to 100,000 total denier are given from 4 to 6 crimps per centimetre and arranged as a band 6 to 10 inches wide which is tensioned to reduce the fibre crimps to 2 to 3 per centimetre, regenerated cellulose or an aqueous solution of ethyl cellulose being then sprayed on one or both band surfaces to fuse the interminged fibres together at random points of contact and form a felted fabric from 0,75 mm. to 1 mm. thick and weighing 60 to 70 grams per sq. metre which if necessary is dried by hot air jets or infra-red rays and which has a greater stiffness axially than laterally.  The fabric may be overlaid with single or multiple ply cellulose wadding on one or both sides, the combined fabric being integrated by passage through a pair of profiled rollers which may be cold or heated by electricity or steam and which give the finished product axial indented lines at a spacing of from 4 to 6 per inch.  The fabric may be formed into lengths of cigarette filter plug rod by wrapping and cutting it in a conventional continuous-rod cigarette-making machine, in place of the normal tobacco rod, after bunching it by passing it through a folder.
